According to dictionary.reference.com, an Organic LED (OLED) is an “organic light-emitting diode: a light-emitting diode (LED) composed of one or more layers of organic material between two electrodes.”


Because OLEDs work without a backlight, they can display deep black levels. OLEDs can be very thin and lightweight compared to LCDs. Additionally OLEDs can provide a much higher contrast ratio than LCDs.

Unlike regular LEDs, OLEDs have a much shorter lifetime. This is because of the organic material used in them. In fact, one 2008 technical report on an OLED TV panel found that "After 1,000 hours the blue luminance degraded by 12%, the red by 7% and the green by 8%."

As far as the power consumption goes, OLEDs use far less power than LCDs. It’s worth noting that OLEDs displaying white use about three times more power than displaying black.

Due to their high light output and readability, OLEDs are primarily used in TVs, tablets, watches and phones. The Apple Watch uses an OLED display covered by a sapphire crystal, apparently giving it superior quality over other watch makers.

The topic of Organic LEDs is very big. If you would like to know more about OLEDs or simply think I have missed something, please leave a comment.
